Determine whether the equation is li equation by finding and plotting orde 4x-y=3

Answer:

slope = - [tex]\frac{10}{7}[/tex]

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 5 ) and (x₂, y₂ ) = (5, - 5 )

m = [tex]\frac{-5-5}{5-(-2)}[/tex] = [tex]\frac{-10}{5+2}[/tex] = - [tex]\frac{10}{7}[/tex]

The value of the ratio t:m:w in its simplest form is 3:8:28.

To simplify the ratio t:m:w, we need to find the common factor between t, m, and w.

Using the given ratios, we can write t:m:w as (3x):(8x):(28y), where x is the common factor between t and m and y is the common factor between m and w.

From the given ratio t : m = 3:8, we can say that t is equal to 3 and m is equal to 8.

Similarly, from the given ratio m:w = 4:7, we can say that m is equal to 4 and w is equal to 7.

So, we have

t : m = 3:8 and m:w = 4:7

Multuiply second by 2

t : m = 3:8 and m:w = 8:14

So, we have

t : m : w = 3 : 8 : 14

The type of sampling used to conduct a study on depression among the elderly is convenience sampling, which is a type of non-probability sampling technique where samples are selected because they are conveniently available and accessible, and the sample size for this study was calculated to be 30.

The type of sampling used to conduct a study on depression among the elderly is convenience sampling. Convenience sampling is a type of non-probability non-probability  where samples are selected because they are conveniently available and accessible .

In this study, a sample of 30 patients in one nursing home was used for the convenience sampling. The formula for calculating the sample size for convenience sampling is [tex]N = (N1*N2)/(N1+N2[/tex]), where N is the sample size, N1 is the population size, and N2 is the desired sample size. In this case, N1 is the total number of elderly patients in the nursing home, and N2 is 30. Therefore, the sample size for this study is calculated as follows: [tex]N = (N1*30)/(N1+30) = 30[/tex].

Convenience sampling is a quick and easy way of obtaining a sample, but it can be biased due to the presence of sampling errors and selection bias. Sampling errors occur when the sample is not representative of the overall population, while selection bias occurs when certain groups of people are more likely to be included in the sample than others. Therefore, it is important to consider the potential sources of bias when conducting a study using convenience sampling.

Answer:

To eliminate x, add the two equations together:

5x + 4y = -7

(-5x - 2y = 1)

2y = -6

Solve for y:

2y = -6

y = -3

Substitute y = -3 into one of the original equations, say -5x - 2y = 1, and solve for x:

-5x - 2y = 1

-5x - 2(-3) = 1

-5x + 6 = 1

-5x = -5

x = 1

Therefore, the solution is (x, y) = (1, -3).

Alex does not have enough strawberries to make fruit salad and jam.

A mixed fraction is a fraction that is created by fusing a fraction with a whole number.

An improper fraction is a fraction that cannot be further simplified and has a numerator higher than or equal to the denominator. For instance, 13/5 is a bad fraction. Let's find the mixed fraction equivalent of this incorrect fraction. Divide the denominator by the numerator in step 1. Step 2: Track down the rest. In step 3, arrange the numbers as follows: quotient, followed by a portion of the remainder or divisor.

Given that, Alex wants to use 1 3/4 and 3 1/2 cups of strawberries.

Thus the total strawberries are:

1 3/4 + 3 1/2

= 7/4 + 7/2

Taking LCM we have:

= 21/4 = 5.2 cups

Hence, Alex does not have enough strawberries to make fruit salad and jam.

How does diameter work?

the distance that a straight line must travel in order to connect two points on opposite edges of a circular object or shape The diameter is twice as large as the radius. The pond's circumference is six feet.

Since the circle's centre is on the y-axis, its x-coordinate is zero. Moreover, the circle's radius is 6 units because its diameter is 12 units.

As a result, the equations that depict circles with a centre on the y-axis and a diameter of 12 units are as follows:

(x-0)² + (y-h)² = r², where h is the y-coordinate of the center and r is the radius of the circle.

(x-0)² + (y-k)² = r², where k is the y-coordinate of the center and r is the radius of the circle.

2 = r2, where k is the circle's center's y-coordinate and r is its radius.

We can see from these equations that circles with a diameter of 12 units and a centre on the y-axis are represented by the following equations:

x² + (y-6)² = 36 (center at (0,6))

x² + (y+6)² = 36 (center at (0,-6))

As a result, the following choices depict circles that satisfy these requirements:

x² + (y-6)² = 36

x² + (y+8)² = 36

The appropriate choices are thus:

x² + (y-6)² = 36

Given a starting point of (-4, 3), if move 2 units up and 6 units right, you will end up at the point (2,5).

A point in a coordinate system has two coordinates - an x-coordinate and a y-coordinate.

The x-coordinate tells you how far to move horizontally from the origin (0,0), and the y-coordinate tells you how far to move vertically from the origin.

Given the point (-4,3) means that you start at the point that is 4 units to the left of the origin and 3 units above the origin.

Now, moving 2 units up from (-4,3), you will end up at the point that is 2 units higher on the y-axis.

So, your new y-coordinate will be 3 + 2 = 5.

When you move 6 units right from (-4,3), you will end up at the point that is 6 units to the right on the x-axis.

So, your new x-coordinate will be -4 + 6 = 2.

Therefore, you end up at the point (2,5).

We can use the Pythagorean theorem to find the diagonal distance across the rug. According to the theorem, the sum of the squares of the two shorter sides of a right triangle is equal to the square of the longest side (the hypotenuse).

In this case, the length and width of the rug form the two shorter sides of a right triangle, and the diagonal distance is the hypotenuse. So we can use the formula:

diagonal^2 = length^2 + width^2

Plugging in the values given in the problem, we get:

diagonal^2 = 8^2 + 5^2

diagonal^2 = 64 + 25

diagonal^2 = 89

To solve for the diagonal, we take the square root of both sides:

diagonal = sqrt(89)

Using a calculator, we get:

diagonal ≈ 9.43 feet

Therefore, the diagonal distance across the rug is approximately 9.43 feet.

Step-by-step explanation:

The ramp will rise 20.79 inches from the ground at its highest end.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's assume that the ramp will be in the shape of a right triangle, where the length of the base (the horizontal distance from the ground to the highest end of the ramp) is 36 inches and the angle between the base and the hypotenuse (the ramp itself) is 30 degrees.

We can use trigonometry to find the height of the ramp (the vertical distance from the ground to the highest end of the ramp).

First, we need to find the length of the hypotenuse. We can use the formula:

hypotenuse = base / cosine(angle)

In this case, the base is 36 inches and the angle is 30 degrees, so:

hypotenuse = 36 / cosine(30) = 41.57 inches (rounded to the nearest hundredth)

Next, we can use the formula for the sine of an angle:

sine(angle) = opposite / hypotenuse

In this case, the opposite side (the height of the ramp) is what we want to find. So we can rearrange the formula to solve for the height:

height = sine(angle) x hypotenuse

Plugging in the values we know, we get:

height = sine(30) x 41.57 = 20.79 inches (rounded to the nearest hundredth)

Therefore, the ramp will rise 20.79 inches from the ground at its highest end.

The sum of the geometric series is 513.

To find the sum of a geometric series, we use the formula:

S_n = a[tex](1-r^{n})[/tex] / (1 - r)

where S is the sum of the first n terms, a is the first term, r is the common ratio, and n is the number of terms.

In this case, we know that the first term is 3, and the common ratio is -2. To find the number of terms, we need to determine what value of n satisfies the equation:

768 = 3 x [tex](-2^{n-1} )[/tex]

We can simplify this equation by dividing both sides by 3:

256 = [tex](-2^{n-1} )[/tex]

Taking the logarithm of both sides (to base 2), we get:

n - 1 = [tex]log_{2}[/tex](256)

n - 1 = 8

n = 9

Therefore, there are 9 terms in the series for this question.

Using the formula for the sum of a geometric series, we have:

S = 3(1 - [tex](-2^{9} )[/tex] / (1 - (-2))

S = 3(1 - (-512)) / 3

Therefore, there are no planes that are equidistant from all four vertices of a tetrahedron.

To further explain, let's consider the four distances from the vertices A, B, C, and D to a plane P. If all four distances are the same, then the plane P must be equidistant from all four vertices.
